This paper considers the problem of inferring the dimensions of non-visible body parts from images of incomplete bodies. This situation often occurs in CCTV videos of crowded scenes where people are mostly occluded. The approach we present relies on the ability to measure an observable body part which correlates to a missing body part. Anthropometric regression equations are then used to predict the...
Resources allocation and scheduling has been recognised as an important topic for business process execution. However, despite the proven benefits of using Cloud to run business process, users lack guidance for choosing between multiple offering while taking into account several objectives which are often conflicting. Moreover, when running business processes it is difficult to automate all tasks...
Pedagogically, feedback in CAPT systems can be improved by focusing on the most critical errors rather than presenting all errors to the users at the same time. This paper presents our work on the use of crowdsourcing for collection of gradations of word-level mispronunciations in non-native English speech. Quality control procedures based on the proposed WorkerRank algorithm (adapted from well-known...
Our aim is to develop an algebraic approach to estimate human posture in the sagittal plane using Inertial Measurement Unit (IMU) providing accelerations and angular velocities. For this purpose, we address the issue of the estimation of the amplitude, frequency and phase of a biased and noisy sum of three sinusoidal waveform signals on a moving time horizon. The length of the time window being small,...
Customer store loyalty is one of the most important motivations that facilitate the intentions of re-patronizing a retailer's website and create marketing values for firms. Research on survey-based for measuring consumers' loyalty to persist in online shopping environment has been developed. But while the measured values of human perceptions towards various attributes are often uncertain data, most...
This paper shows a method of WDR (wide dynamic range) in camera. When we make a digital WDR, commonly we meet two problems. The first one is an increase of noise. And the other is a lot of control factors. In this paper we will show a WDR with low noise and small number of control factors. The circuit is very simple and needs no memory. So the chip size is nearly unchanged after implementation. When...
One of the challenges in mixed reality (MR) applications is handling contradictory occlusions between real and virtual objects. The previous studies have tried to solve the occlusion problem by extracting the foreground region from the real image. However, real-time occlusion handling is still difficult since it takes too much computational cost to precisely segment foreground regions in a complex...
In our research, we aim to construct a house-keeping robot system which folds laundry. And, we propose a way for folding clothes without vision sensing device. To realize this system, we prepare appropriate fixed folding motion. We analyzed cloth folding motions by human. And, we found fixed folding motion pattern for the robot. Furthermore, we generated a trajectory of folding motion which is applicable...
This paper puts forward an information dissemination model on social network. A framework is presented to understand human impacts on information dissemination, which are generalized as a utility function, several factors shaping human behavior are involved, such as knowledge, belief, persuasion, memory and reputation. Each individual in the network is considered as either sender or receiver, who...
This paper proposes a detection method for electronic parts from electronic board images using HSV color format. In this study, we can pick out the electronic parts images by dividing the fixed section. If the parts have a low level of saturation, we detect only two colors that as black and white. To use this method, the detection rate of other colors is improved. It is possible to detect the region...
This paper presents a socio-demographic model defined by sexes and structured by age. The model is a von Foerster-McKendrick model for the dynamics of population by sex and age of a general human population. The fertility and deaths rates are structured by age and they depend on the well-being variable. The well-being variable is defined by UN, HDI-Hybrid. We present the validation of the stochastic...
Safeguards and security systems for nuclear facilities include material control and accounting (MC&A) and a physical protection system (PPS) to protect against theft, sabotage and other malevolent human acts. The insider threat is most often addressed as part of the evaluation of a facility's PPS. A PPS is evaluated using probabilistic analysis of adversary paths on the basis of detection, delay,...
In this paper, we connect local properties in a mobile planar multi-robot team to the task of creating decentralized real time algorithmic music. Using a nonlinear formation control law inspired by the consensus equation, we map the local motion parameters of robots to Euclidean rhythms with the use of sequencers. The control parameters allow a human user to direct this decentralized musical process...
In this paper, we propose a method for representing “neighborhoods” of moving objects such as people. By using neighborhoods, it is possible to determine whether the spatial relations between objects and their surrounding spatial information are strong. It can be said that a neighborhood is the spatial area of an object's attention, interest or concern. It is preferable that neighborhoods move while...
In this research, an approach to optimize motions for a humanoids is presented. Rapidly-exploring Random Tree(RRT) were used to plan an initial suboptimal motion. A reinforcement learning was then implemented to optimize the trajectories with respect to energy consumption, similarity to a human's natural motion and, physical limits. Energy cost was estimated by joint torque from a dynamic model, and...
Human is capable of adaptive and supple locomotion in the real world characterized by rapid changes, high uncertainly, and limited availability of information. In order to understand the human walking, this work was motivated by the concept of passive dynamic walking robots, which have no actuation or control system except for gravity are capable of stable, human-looking walking. On the other hand,...
We propose a mathematical model for optimizing pixel aspect ratio for the best 3D estimation in both stereo-based 3D reconstruction and 3D viewing applications. We analyze the 3D reconstruction through a 3D display medium and reduce the whole process to a single stereo system so that a unified model can be applied to both direct reconstruction from stereo images and indirect reconstruction through...
This study focuses on joint motion patterns of humans that move together with other humans or objects. Since this scope embraces ‘group motion’, which relates only humans, and expands its extent of interactions accounting for various auxiliary instruments such as walking aids or pushcarts, we term this collective motion pattern as ‘coherent’ motion. Coherence is proposed to be characterized by the...
The interiors of mass transit vehicles act as pseudo-reverberant environments which are loaded by the bodies of passengers. This study models the broadband loading characteristics of the human body, first by simulation with spherical approximations, then by measurement of nine human subjects in a reverberation chamber. The absorption cross-section of the subjects is calculated from the loaded and...
With the development of mobile web integration technologies and wireless sensor networks, the interactive activities of human society increasingly rely on the heterogeneous network environment including the communication network, the Internet and sensor networks. This paper tries to apply socially aware computing and data mining to the mobile web application integration technology. It emphasizes understanding...
